The ideal candidate brings strong Tableau and Power BI and SQL skills, hands-on experience with data modeling and DAX, and the ability to work effectively across technical and business teams in a fast-paced, Agile environment.

Key Responsibilities : Semantic Model Design, Solution architecting and Implementation : o Architect and maintain robust data models (datasets) with clearly defined measures, hierarchies, and calculated columns. o Ensure adherence to modeling best practices, including the use of fact and dimension tables, role-playing dimensions, surrogate keys, and bi-directional filtering when appropriate. o Design optimized relationships and data granularity alignment across tables to support accurate aggregations and slicing / filtering. o Derive various model storage architectural patterns to fit into DW and DataLake data landscape having performant and scalable model architecture. o Good understanding of multi-Cloud Data architecture within AWS and Azure, cross cloud networking, data egress, data integration using Gateway installer to best design semantic model architecture. o Understanding of Business Objects universe functionalities and BI platform migration from BO to Power BI is an added advantage. o Build Tableau Data Model and relationships with star / snowflake schema architecture, understanding on semantic model build and tableau semantics tool. o Utilize Tableau PREP for data shaping, transformation, and cleansing while ensuring query folding is preserved in DirectQuery mode. o Collaborate with data engineers to validate source-to-model mapping, and offload heavy transformation logic to upstream pipelines (e.g., Dataflows, Fabric, or SQL views) where appropriate. o Ensure data lineage, traceability, and refresh reliability throughout the modeling layer. o Use external tableau extensions like Super Table / Tableau Table to build paginated pixel perfect report having excel functions built-in.

Data Skills

• SQL Writing queries, joins, and aggregations to retrieve and prepare data for Tableau.
• Data Modeling Understanding relationships, joins, blends, and data sources and efficiently handling large datasets.
• Data Cleaning Identifying and fixing data quality issues before visualization.
• Database Connectivity Connecting Tableau to relational databases (MySQL, SQL Server, Oracle), cloud platforms (Redshift, S3 Data Lake), and APIs.
